ITGI pipeline


The ITGI (Interconnector Turkey-Greece-Italy) System is a multi-source import project that will contribute to the European diversification and security of supply by opening the so called “Southern Gas Corridor”. The pipeline is designed to transport approximately 15 billion cubic metres of natural gas a year from Caspian, East Med and/or Middle East areas to Italy and Europe through Turkey and Greece.

The route

The project comprises the following pipeline sections:

  • Turkish grid, which will be upgraded in order to enable the transit of gas volumes for Italy and Greece
  • ITG (Interconnector Turkey-Greece) which is in operation since November 2007 and has a transport capacity of about 11.5 billion cubic metres of natural gas a year
  • IGI (Interconnector Greece-Italy) project with a transport capacity of about 12 billion cubic metres of natural gas a year. IGI pipeline will be 800 kilometres long and includes:
  • IGI Onshore: 600 km onshore pipeline in the Greek territory (to be developed by Desfa, the Greek Transmission System Operator);
  • IGI Poseidon: 200 km offshore pipeline across the Ionian Sea (under development by IGI Poseidon SA, a joint venture between Edison and the Greek company Depa).

A strategic project for Italy and Europe

ITGI pipeline is a Project of Common Interest as it was included among the Southern Gas Corridor Projects in the European Economy Recovery Plan with a 100 million Euros financing. Italy-Greece section of the ITGI pipeline was granted 25 years TPA Exemption (Art. 22 of Directive 55/2003)

Key benefits of the ITGI project

  • Most of the infrastructures required by the ITGI Project are already in operation, so it’s the cheapest and fastest way to open the Southern Gas Corridor.
  • Since the project is not sponsored by main gas producers, different sources of supplies could be transported. It implement the EU strategy for enhancing security of supply in South Europe and Balkan countries
  • It enables Solidarity mechanisms to Greece and South East Europe Countries, through reverse flow opportunities from Italy.
  • Needed intergovernmental agreements are already signed

Intergovernmental agreements

  • November 2005 - Intergovernmental Agreement between Greece and Italy, defining the commitment of the Parties to support the realization of the Project, by means of identifying the legal framework for the offshore section and the need of securing the TPA exemption.
  • July 2007 - Intergovernmental Agreement among Turkey, Greece and Italy in which also Turkey agrees to provide transit services based on cost reflective principles for the volumes to Italy and Greece.
  • August 2007 - Memorandum of Cooperation between Greece and Azerbaijan establishing the interest in supply agreements for volumes destined to Italy via the Poseidon Pipeline.
  • December 2007 - Protocol of Agreement between Italy and Azerbaijan supporting gas supply negotiation between Socar and Edison for ITGI project capacity.
  • June 2010 - Memorandum of Understanding among Edison, Depa and Botas which draws the framework for the transit through Turkey of the natural gas for the ITGI pipeline.
